Floating columns are a typical feature in the modern multi-storey construction in urban India and are highly undesirable in buildings built in seismically active areas. In this paper static analysis is done for a multi-storey building with and without floating columns. Different cases of the building are studied by varying the location of floating columns floor wise. The structural response of the building models with respect to, Base shear, and Storey displacements is investigated. The analysis is carried out using software sap2000v17.

Analysis and design of multi-storey building using staad.Progsharda123
This document presents a minor project report on the analysis and design of a four-storey building (ground plus three floors) using STAAD Pro software. It was submitted by five civil engineering students at Guru Nanak Dev Engineering College, Punjab, India in partial fulfillment of their Bachelor of Technology degree. The report covers various topics related to structural analysis and design including different analysis methods, design of building elements like slabs, beams, columns, and footings. It also discusses assumptions, design codes, loads, and materials used for the building design.
The document discusses the different types of loads that act on structures. It classifies loads as vertical loads (dead load, live load, impact load), horizontal loads (wind load, earthquake load), and longitudinal loads (tractive and braking forces). The main vertical loads are dead load from structural members and materials, live load from occupancy, and impact load from vibrations. The primary horizontal loads are wind load from air movement and earthquake load from seismic activity. Longitudinal loads apply specifically to bridges and gantries. The document provides further details on the characteristics and calculation of common load types like dead load, live load, snow load, impact load, wind load, and earthquake load.
Composite structure of concrete and steel.Suhailkhan204
This document discusses composite structures, which combine steel and concrete materials. The key elements of composite structures are composite deck slabs, beams, and columns, along with shear connectors. Composite structures take advantage of concrete's compressive strength and steel's tensile strength. They provide benefits like increased load capacity, stiffness, fire resistance, and cost savings compared to traditional steel or concrete construction alone. An example project, the Millennium Tower in Vienna, is described. The document analyzes costs and concludes that composite structures are best suited for high-rise buildings due to reduced weight, increased ductility, and savings of around 10% compared to reinforced concrete.

Braced steel frames are commonly used to resist lateral loads from earthquakes. There are two main types of bracing configurations: concentric and eccentric. Cross bracing provides the highest lateral stiffness compared to diagonal bracing or unbraced frames. Analysis of a sample braced steel frame model found that cross bracing reduced story drift by 87% and column shear and bending moments compared to an unbraced frame. However, axial forces in the columns increased with the addition of bracing. Response spectrum analysis accounted for multiple vibration modes while time history analysis used specific earthquake acceleration records over time. Cross bracing consistently performed best at reducing lateral deformation and forces in the frame.
This presentation summarizes torsion and torsional diagrams. It defines torsion as the twisting of an object due to an applied torque. A torsional diagram is a two-dimensional representation of torque along an object. The presentation discusses assumptions of torsion theory, sign conventions, torsion loading, torsion formulas, failure modes, and provides a summary of key points like the highest shear stress occurring on the surface of a shaft. It was presented to fulfill the requirements of a pre-stressed concrete course.
The document discusses ductility and ductile detailing in reinforced concrete structures. It states that structures should be designed to have lateral strength, deformability, and ductility to resist earthquakes with limited damage and no collapse. Ductility allows structures to develop their full strength through internal force redistribution. Detailing of reinforcement is important to avoid brittle failure and induce ductile behavior by allowing steel to yield in a controlled manner. Shear walls are also discussed as vertical reinforced concrete elements that help structures resist earthquake loads in a ductile manner.
Flat slabs are reinforced concrete slabs that are supported directly by columns without beams. They provide minimum depth, fast construction, and flexible column placement. There are four main types: slabs without drops and with column heads, slabs with drops and without column heads, slabs with both drops and column heads, and typical flat slabs. Column heads increase shear strength while drops increase shear strength and negative moment capacity. Flat slab systems can be either one-way or two-way depending on span ratios and load distribution. Advantages include simple formwork, no beams, and minimum depth, while disadvantages include potential interference from drops.

Control System for Navigating a Domestic Droneijceronline
This paper describes the design, building and testing of a Drone Flight Navigation (DFN) system used to control the movement of livestock away from the ploughing fields. The inputs to the DFN system include different sounds of livestock to be removed from the fields. The output of the system will be the irritating sounds to the livestock and also deploy a rotating umbrella-like cloth and flashing LED lights to scare the animals even more. The input and output sounds are stored in a database and can be updated with preferred sounds. We have successfully simulated and programmed a prototype DFN system using ALTERA UP1 Development Board. Also on this paper, we discussed drone power management system (DPMS) which ensures that the drone has enough battery power before each flight. For future developments, GPS and video camera capabilities can also be included into the design so that the farmer will be able to observe what the system is seeing and possibly give live instructions

IRJET- Experimental Study of Floating Column for Seismic Analysis of Multisto...IRJET Journal
This document summarizes an experimental study on the seismic analysis of a multi-story building with and without floating columns. Four building models were created - one without floating columns, and the others with a floating column at the 1st, 2nd, and 3rd floors. The models were analyzed using software to compare the base shear and story displacements under seismic loads. The results showed that buildings with floating columns experienced greater displacements and base shear compared to the building without floating columns, with the highest values for the model with a floating column at the 3rd floor. The study aims to evaluate the effect of floating columns on building behavior during earthquakes.
COMPARATIVE SEISMIC ANALYSIS OF A MULTI-STOREY RCC STRUCTURE WITH & WITHOUT F...IRJET Journal
This document discusses a comparative seismic analysis of a multi-storey reinforced concrete structure with and without floating columns located in seismic Zone IV, using computer software ETABS. Four cases are analyzed: Case 1 with no floating columns, and Cases 2-4 with floating columns at different locations on the ground floor. Parameters compared include storey drift, displacement, and shear. Results show that the presence of floating columns increases storey drift and displacement due to discontinuity in load transfer, with interior floating columns performing better than exterior columns. The study seeks to evaluate the impact of floating columns on the structure's seismic performance and response.
“A REVIEW STUDY ON PUSHOVER ANALYSIS OF SYMMETRIC BUILDING ON FLAT & SLOPING ...IRJET Journal
This document summarizes pushover analysis that was conducted on symmetric buildings located on flat and sloping surfaces. Pushover analysis using ETABS software evaluated how dynamic features like base shear, roof displacement, and hinge formation differed between building models. Previous studies on pushover analysis of buildings on sloping ground with or without soil-structure interaction were also reviewed. The analysis found that buildings on sloping surfaces experienced less displacement and softer story drift compared to equivalent buildings on flat surfaces. Hinge conditions at the performance point provided insights into the structural response.
Earthquake Resistant Design of Low-Rise Open Ground Storey Framed BuildingIJMER
This document discusses the earthquake resistant design of low-rise buildings with open ground stories (OGS). It aims to study the effect of infill wall stiffness and support conditions on the seismic behavior of OGS buildings. A 4-story reinforced concrete building located in seismic zone 5 of India is modeled with and without considering infill walls. Both linear and nonlinear analyses are performed. The results show that considering infill wall stiffness reduces seismic demands on ground story columns and beams compared to models without infills. A force amplification factor of 2.5 applied to the ground story in current standards is found to be too conservative for low-rise OGS buildings. Support conditions also influence the building response, with fixed supports resulting in greater period shifts

Comparative study on multistoried building using linear and non linear analysisIJARIIT
The effect of infill walls on the building is generally neglected in the analysis. In fact, an infill wall contributes to the
lateral strength and stiffness of the structure. Seismic response analysis of multi storey building frame with infill was done by
modeling the infill wall as an equivalent diagonal strut. For the equivalent diagonal strut, the thickness is taken equal to the
thickness of the wall and width of the strut as per “Equivalent strut method”. The comparison of seismic responses is done for
the multi-storied buildings with infill as equivalent diagonal strut using linear and non-linear analysis. ETABS software is used
for the present study.
IRJET- Comparative Study of Effect of Different Positions of Shear Wall o...IRJET Journal
This document presents a comparative study analyzing the effect of different positions of shear walls on transfer girders in 10, 15, 20, 25, and 30-story reinforced concrete buildings with floating columns on the exterior frames. The buildings were analyzed using wind analysis, conventional analysis, and construction stage analysis in ETABS. Results like bending moments and displacements of the transfer girders were compared for models with shear walls at the core, corners, periphery, and without shear walls. The study found that shear walls at different positions reduced structural responses of the transfer girders, with core walls performing best for lower stories and corner walls for mid-height buildings. Conventional analysis generally provided the critical results adopted for design.
1) The document discusses analyzing the effect of stiffness on different shapes of buildings for seismic zones. It focuses on modeling and analyzing a 5-story reinforced concrete building with rectangular, H, L, and T-shaped plans using STAAD Pro software.
2) 20 models with variations in plan geometry (rectangular, H, L, T-shapes), column shape (square, rectangular, T-shape), and column orientation are created. The buildings are located in seismic zone IV and modeled according to Indian code IS 1893:2002.
3) Results like maximum displacement, base shear, and stiffness are obtained and will be used to understand how plan geometry impacts seismic performance and which shapes exhibit better seismic resistance.
Effect of modeling of infill walls on performance of multi story rc buildingIAEME Publication
This document summarizes a study on the effect of modeling masonry infill walls in multi-story reinforced concrete buildings. Three models of an 8-story building were analyzed: a bare frame, a frame with infill excluding the ground floor to create a soft story, and a frame with full infill. Nonlinear static pushover analysis was performed on the models. The results showed that modeling full infill improved seismic performance by increasing base shear and stiffness, distributing plastic hinges elastically throughout the structure. The bare frame and soft-story structure had plastic hinges form in the life safety to collapse prevention range, indicating poorer performance, while the full infill structure remained elastic. Therefore, modeling infill walls more

This document summarizes a research paper that analyzes the pushover analysis of setback frame and step frame buildings with and without shear walls using ETABS software. It presents 8 building models including a regular frame, 3 types of step frames with varying setback ratios, and 4 types of setback frames with varying ratios. Nonlinear static (pushover) analysis is performed using response spectrum analysis to understand the performance of irregular frames compared to regular frames in seismic zone III of India. Key response parameters like base shear, story displacement, and story drift are examined. The study aims to provide guidelines for seismic-resistant design of irregular structures.
Seismic Response of Vertically Irregular Structure with Composite ColumnsIRJET Journal
This document discusses the seismic response of vertically irregular structures with composite columns compared to regular structures. Three models of buildings with different vertical irregularities are modeled and analyzed using ETABS software. The models include the same building with and without composite columns. Results show that structures with composite columns have higher displacements but lower base shear and story drift compared to corresponding irregular structures without composite columns. This indicates that use of composite columns can improve seismic performance by increasing flexibility and reducing failure of irregular structures during earthquakes.

This document analyzes a 15-story residential building with and without shear walls using response spectrum analysis. It finds that placing symmetrically positioned shear walls improves the building's performance in terms of seismic parameters like story drift, displacement, forces and stiffness compared to a building without shear walls. The building is modeled in ETABS software and seismic parameters are compared for models with and without shear walls in zone 3. Results show that shear walls enhance the building's lateral stiffness and resistance to earthquake forces.
This document presents the results of a study that used finite element analysis to evaluate the seismic performance of three-story and six-story buildings with plus-shaped shear walls. The study compared the results of equivalent static analysis, response spectrum analysis, and nonlinear static pushover analysis based on guidelines in Indian seismic codes. The pushover analysis was found to provide more accurate predictions of structural response compared to the linear analysis methods by accounting for nonlinear material behavior and P-delta effects. Increasing the building height from three to six stories increased the structural drift and base shear obtained from the analyses.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

ABSTRACT
Floating columns are a typical feature in the modern multi-storey construction in urban India and are highly
undesirable in buildings built in seismically active areas. In this paper static analysis is done for a multi-storey
building with and without floating columns. Different cases of the building are studied by varying the location
of floating columns floor wise. The structural response of the building models with respect to, Base shear, and
Storey displacements is investigated. The analysis is carried out using software sap2000v17.
Keywords: Floating column , linear static analysis , sap2000v17.
I. NTRODUCTION
In recent times, multi-storey buildings in
urban cities are required to have column free space
due to shortage of space, population and also for
aesthetic and functional requirements. For this
buildings are provided with floating columns at one
or more storey. These floating columns are highly
disadvantageous in a building built in seismically
active areas. The earthquake forces that are
developed at different floor levels in a building
need to be carried down along the height to the
ground by the shortest path. Deviation or
discontinuity in this load transfer path results in
poor performance of the building. The behavior of
a building during earthquakes depends critically on
its overall shape, size and geometry, in addition to
how the earthquake forces are carried to the
ground. Many buildings with an open ground
storey intended for parking collapsed or were
severely damaged in Gujarat during the 2001 Bhuj
earthquake.[1]
Floating Column: The floating column is
a vertical member which rest on a beam and
doesn’t have a foundation. The floating column act
as a point load on the beam and this beam transfers
the load to the columns below it.[4]

1.Sukumar Behera*In this paper involve stiffness
balance of first storey and the storey above are
studied to reduce irregularity occurs due to
presence floating column. To study response of
structures under different earthquake excitation
having different frequency content keeping the
PGA and time duration factor constant they
develop FEM codes for 2D frames with and
without floating column. The behavior of building
frame with and without floating column is studied
under static load, free vibration and forced
vibration condition. The finite element code has
been developed in MATLAB platform. The time
history of floor displacement, inter storey drift,
base shear, overturning moment are computed for
both the frames with and without floating column.
The dynamic analysis of frame is studied by
varying the column dimension. It is concluded that
with increase in ground floor column the maximum
displacement, inter storey drift values are reducing.
The base shear and overturning moment vary with
the change in column dimension.[1]
